Re: CFileDialog and CFile::Open RobJones28-Nov-01 6:35 RobJones 28-Nov-01 6:35  It appears that the CFile::Seek function is throwing the error.. Any ideas why? It's like it can't find the end of the file. Is there any trouble shooting methods that I can use to determine the cause of the exception? Thanks again for you help! Rob Re: CFileDialog and CFile::Open RobJones28-Nov-01 9:19 RobJones 28-Nov-01 9:19  I don't usually reply to my own msg's but I figured everything out.. so disregard my last few posts.. Thanks, Rob Re: CFileDialog and CFile::Open 28-Nov-01 14:27 28-Nov-01 14:27  Are you sure, that the file is opened properly ??? For a better error description you might use SDK functions CreateFile, ReadFile, CloseHandle and GetLastError instead of mfc. And perhaps a work-around: Get the file length, move to byte position (FileLength-128) from start, read the last lines ... But to be honest, I don`t believe that it is the Seek which really causes the trouble here... Regards, Marco GetDiskFreeSpaceEx RickyC28-Nov-01 5:22 RickyC 28-Nov-01 5:22  Hy everyone, I'm tryng to do an application that show in some window the current amount of memory in the user's hard disc. But when the user is using win 95 before OSR2 the function GetDiskFreeSpaceEx must be replaced by GetDiskFreeSpace, and the MSDN Library tell's me to "you should dynamically link to it via GetProcAddress"... I do everything they tell me to do... but in win 95 my program do not work... causes an error on kernel32.dll that can't find de GetDiskFreeSpaceExA... please, if someone can help me it's will be great! I'll post an part of my code that I do the implementation of the MSDN Library: P_GDFSE pGetDiskFreeSpaceEx = NULL; pGetDiskFreeSpaceEx = (P_GDFSE)GetProcAddress (GetModuleHandle ("kernel32.dll"),"GetDiskFreeSpaceExA"); if(pGetDiskFreeSpaceEx) { fresult = GetDiskFreeSpaceEx (windowsDir, (PULARGE_INTEGER)&FreeBytesToCaller, (PULARGE_INTEGER)&TotalBytes, (PULARGE_INTEGER)&FreeBytes); m_strDirSistema = _T( windowsDir ); m_dwQuotaLivreUsuario = /*(DWORD*/FreeBytesToCaller / MEGABYTE; // this lines given - me warnings of conversion but it's work correctly m_dwEspacoTotal = /*(DWORD)*/TotalBytes / MEGABYTE; m_dwEspacoLivre = /*(DWORD)*/FreeBytes /MEGABYTE; } thanks all, for the attention! cheers!! and sorry my english, I'm brazilian Re: GetDiskFreeSpaceEx Jon Hulatt28-Nov-01 5:47 Jon Hulatt 28-Nov-01 5:47  You say that "MSDN Library tell's" [you to] "dynamically link to it via GetProcAddress" But in your code, you're trying to dynamically link to GetDiskFreeSpaceExA, not GetDiskFreeSpace. Sorry to dissapoint you all with my lack of a witty or poignant signature.

It does nothin of that sort It says "To determine whether GetDiskFreeSpaceEx is available, call the LoadLibrary or LoadLibraryEx function to load the KERNEL32.DLL file, then call the GetProcAddress function to obtain an address for GetDiskFreeSpaceEx. If GetProcAddress fails, or if GetDiskFreeSpaceEx fails with the ERROR_CALL_NOT_IMPLEMENTED code, use the GetDiskFreeSpace function instead of GetDiskFreeSpaceEx" so since you are sure you are on pre-osr2 win 95 dont bother using the GetDiskFreeSpaceEx call and stick to using GetDiskFreeSpace Nish Sonork ID 100.9786 voidmain www.busterboy.org If you don't find me on CP, I'll be at Bob's HungOut Re: GetDiskFreeSpaceEx RickyC28-Nov-01 6:19 RickyC 28-Nov-01 6:19  Hy, I'm new to MFC... and don't know much... but in my MSDN Library (january 2001) has something like this: /* Use GetDiskFreeSpaceEx if available; otherwise, use GetDiskFreeSpace. Note: Since GetDiskFreeSpaceEx is not in Windows 95 Retail, we dynamically link to it and only call it if it is present. We don't need to call LoadLibrary on KERNEL32.DLL because it is already loaded into every Win32 process's address space. */ pGetDiskFreeSpaceEx = (P_GDFSE)GetProcAddress ( GetModuleHandle ("kernel32.dll"), "GetDiskFreeSpaceExA"); if (pGetDiskFreeSpaceEx) { fResult = pGetDiskFreeSpaceEx (pszDrive, (PULARGE_INTEGER)&i64FreeBytesToCaller, (PULARGE_INTEGER)&i64TotalBytes, (PULARGE_INTEGER)&i64FreeBytes); if (fResult) { } } else { fResult = GetDiskFreeSpace (pszDrive, &dwSectPerClust, &dwBytesPerSect, &dwFreeClusters, &dwTotalClusters); if (fResult) { //some code that I'll not put because the space in this page } } if (!fResult) printf ("error: %lu: could not get free space for \"%s\"\n", GetLastError(), argv[1]); } I Just try to follow this... and is not working... sorry if I'm doing something stupid :\ Re: GetDiskFreeSpaceEx Michael Dunn28-Nov-01 8:34 Michael Dunn 28-Nov-01 8:34  Download the latest Platform SDK and #include <newapis.h>. That header has wrappers for GetDiskFreeSpaceEx() and other APIs that handle all that linking nonsense for you. --Mike-- http://home.inreach.com/mdunn/ While I can't be correct on all matters, I can make the reassuring claim that where I am inaccurate, I am at least definitively inaccurate. your with and Sonork - 100.10414 AcidHelm Test out a prerelease build of my Hotfix Checker v2.0!

I have both draw functions implemented in my view and i can switch them with a menu command. For the users simpicity i want to have a view with a tab in it. So the user can switch from view with a single mouse click instead of selecting a menu item. The problem is that i don't know how to implement this in a single view. I would like to have a look and feel like the tabs in visual studio, where you have the tabs to switch from one piece of code to another. Does anybody have any idea on how to do this and has some code to show me. I allready took a look on the site and found this piece of code: http://www.codeproject.com/docview/dynviews.asp. This is allmost what i want. The only thing is that it uses multiple CViews, while i want just one.

In case of a list box, e.g. LBN_SELCHANGE (the selection just changed). Enjoy Peter Re: NMHDR, i need explain !
